ESS - version 18.10.2

How can I get ESS?

Here you can download ESS and related resources

ESS is implemented in the platform-independent programming language Emacs Lisp (eLisp) which is the extension language of Emacs. To run ESS in Emacs you have to first download the compressed eLisp source files and install them according to the following instructions. As different file compression formats are routinely used for different operating systems both <.tgz> (Unix/Linux) and <.zip> (MS Windows) file formats are provided.

ESS - Latest Released Version

• Download ESS Version 18.10.2 (2018-11-10) [zip] [tgz], with crypto signatures for each, [zip.sig] [tgz.sig]
  
  The *.sig files are checking the integrity of the *.zip or *.tgz archive, respectively: You must have gpg installed (GPG: = GNU Privacy Guard : [gnupg.org]), and then in shell (or "a console"), do once (to get the public key with which the archives are signed)

  		    gpg --keyserver hkp://pgp.mit.edu --recv-key 68E0DB0F
  		  

  and then

  		    gpg --verify ess-18.10.zip.sig  ess-18.10.zip
  		 

  whence you should be told that it is a good signature, from an ESS core member, currently Martin Maechler.
  
  You can find the current, as well as previous, released version(s) in the archive.
• Current as well as previous version(s) of ESS are available for download on GitHub [https://github.com/emacs-ess/ESS]
  . In principle, on GitHub, you can download every released version of ESS via their tags. However, inconsistencies (of tags and the released archives (zip, tar.gz) have been observed, and we do not recommend using github to get ESS releases now! Click on a dropdown that shows "master" and select tags. Select one and then "Download Zip".

Installation instructions can be found in the manual.

ESS for Linux

On some distributions of Linux, ESS can be installed as an official RPM package via the package manager. For other distributions, the RPM packages are provided by private users. Please compare the version number of those packages with the latest release.

• Fedora: <emacs-ess> and you should get emacs-ess.
• OpenSUSE, in one of the sub directories openSUSE.../noarch/, (D. Steuer)
• Debian or Debian-derived Linux distributions such as Ubuntu have an uptodate package "ess" since 2008, i.e., from Debian "lenny" and "sid" and Ubuntu "intrepid" (= 8.10) on.

polymode

When you are using R, you may find yourself editing R code that has embedded C/C++, HTML or LaTeX. Or you may simply be reading a help page. Emacs, generally, has one major mode per buffer. So, the syntax highlighting will not be what the user intended. polymode was developed as a helper mode for ESS to fix this. With polymode, R code in the help pages, as well as embedded code from another language, is syntax highlighted correctly.
